Why not closed? Can you add your pom as well, since this seems to be jar dependencies issue. — mavarazy, Oct 10 '15 at 07:19
@mavarazy i am not using maven for this project. I have edited the question to include the list of jars. Please have a look. The is closed as well. — Rahul Vijay, Oct 10 '15 at 07:27

Your classpath is broken. A NoClassDefFoundError means that a class can't be found at runtime. I've checked that spring-data-mongodb-1.8.0.RELEASE.jar contains org.springframework.data.mongodb.repository.config.MongoRepositoryConfigurationExtension. It's strange that your app can't find it, because MongoRepositoryConfigNamespaceHandler is also in the same JAR, implying that your class loader should have it.

Since you're not using Maven, is it possible you just have a corrupted JAR? You can find checksums and file sizes on Maven Central.

I am getting the same error even after re-downloading the JAR. – Rahul Vijay Oct 10 '15 at 09:41
I'd first confirm you really have that class in there, using something like `find . -name "*.jar" -exec tar tvf {} \; | grep MongoRepositoryConfigurationExtension` in the `lib` directory. If that shows the class, then Tomcat isn't seeing the same JARs, and you'll have to figure out why, possibly deployment mechanism (which you haven't described) or some endorsed directory weirdness. – Emerson Farrugia Oct 11 '15 at 09:37

Even-though it is not what you asked for but I will encourage you to leverage build mgt tools like Maven Or Gradle etc, any of those will seamlessly resolve all of the transitive dependencies which could be the issue here and increase your productivity rate tremendously a quick you-tube to get you started with maven

plain spring mvc app pom.xml focus on the mongo dependencies part

Spring boot app pom.xml focus only on the mongo party

In both cases I've used BOM to deal with dependencies versions mismatch as explained here

i created a Maven project and the issue got resolved. Thanks for your suggestion. — Rahul Vijay, Oct 11 '15 at 13:04

I had the same problem yesterday and the only way that I found to fix this was putting the spring-data-mongodb-1.8.0.RELEASE.jar on the lib folder of my tomcat installation, so the server loads it on startup.
